Can't figure this one out. Have put a metal spring deblocker down the pipe but it stops after 2m, I presume it can't get round the bend.
I put chemicals down but the sink still blocks.
The ptrap on the left is clear.
When I pour liquid down the flex pipe on right, if I lift it higher than the exit, liquid seems to run. Yet when I connect it normally, the sink blocks.
Does the level of each pipe look correct?
